'Violence a big problem. Too many children are dying, too many children. We must do something. It will be hard, but the time is now. You must act.' — Former Rep. Gabrielle Giffords (D-Ariz.)

'We take that right very seriously, and we would never, ever give it up – just like Gabby would never relinquish her gun, and I would never relinquish mine. But rights demand responsibility. And this right does not extend to terrorists. It does not extend to criminals. It does not extend to the mentally ill.' — Retired astronaut Mike Kelly, Giffords’ husband.

'The shootings in Newtown should not be used to put into place every gun measure that has been floating around.' — Judiciary Committee Ranking Member Sen. Chuck Grassley (R-Iowa.)

'There should have been a hearing just like this, right after your wife, one of our own, a member of Congress, was shot point blank in the face.' — Sen. Dick Durbin (D-Ill.) to Kelly.

'If we want to save lives right now, not with reforms that might do so some good in the future, there is only one thing that will stop the next copycat killer and that is lawful, armed self-defense in the schools, not only by armed guards, but also by teachers.' — Independence Institute Research Director David Kopel

'Young women are speaking out as to why AR-15 weapons are their weapon of choice. The guns are accurate, they have good handling, they’re light, they’re easy for women to hold. And most importantly, their appearance. An assault weapon in the hands of a young woman defending her babies in her home becomes a defense weapon. And the peace of mind that a woman has as she’s facing three, four, five violent attackers or intruders in her home with her children screaming in the background. The peace of mind from having a big, scary-looking gun gives her courage when she’s facing hardened, violent criminals.' — Independent Women’s Forum Senior Fellow Gayle Trotter

'I do know that six bullets in the hands of a woman trying to defend her children may not be enough.' — Sen. Lindsey Graham (R-S.C.)

'I certainly am willing to give up my right to own a high-capacity magazine to bring that young woman back, that young girl.' — Kelly, speaking about 9-year-old Christina Taylor-Green, who was killed at the Tucson, Ariz. mass shooting in 2011.
